Does anyone have a physical HP-65 that can confirm that for me?

Yes, the result is 20 on a physical 65. As you suspected, when the program encountered the RTN in the A subroutine, it was sent back to finish up the originally executed D subroutine, rather than run sequentially through the other subs.

Oops, I missed that point in the 65 manual.

I rewrote the 65 emulator's Mark and Search code to manage the subroutines in the same way. The emulator now returns 20 as well.
